I called the FRB today and spoke to a very nice woman. After explaining what happened, and after she confirmed that my submission did not go through, she told me that the eFA0-10 is only "officially" compatible with IE 7.0. I told her I'd tried IE9 and the latest Google Chrome, which she told me are "way too current"...with a chuckle. She said I ought to do the paper form, but that it would probably be hard to get one. I have one and explained to her how easily I got it (different story), we had a laugh and that was it. This is the third time in the last few months I've had reason to call the FRB and they've have been extremely helpful. Yes, I know we shouldn't have to go through all this BS, but at least these folks are helpful in spite of the BS.
Just got home and saw Zappa's previous post that he had success with Firefox so I just tried that and worked fine - thanks Zappa!
